Did you check fluid?... Air in the lines... no brake pressure... line broke? Master Cylinder needs replacing?...

its a bit late now but the e-brake is located by your left leg under the dash.

probably a shot master cylinder or failed slave cylinder...check the inside face and inside wall of each wheel and tire. do you see any oil on any of them?

Open the hood and check master cylinder on drivers side firewall. any oil leaking from it. It has a round screw cap on it

e-brake = emergency brake, it's connected mechanically to your rear wheels. Your regular brakes are much differnt, all four corners and pressure is applied through the pedal which forces fluid into the brake cylinders which push the pads on either the disc or drum to slow down the car. It's your regular brakes that failed somehow, if you had applied the e-brake you could have stopped with your rear brakes.

If the pedal just sunk to the floor, and there are no puddles under the car from a broken line or hose, it is your master cylinder. They arent terribly expensive, but do take some knowledge to replace.

if i get into the car now and push brakes they are nice and stiff as usual. it was when i was stopped for a minute or so with the car running and brake being applied did it seem to lose "pressure"?

OH OH!... Point in your story! YOU WERE ON A HILL!... You probably lost pressure because you're low on Fluid! Putting you at an angle made it so it went to one side and was unable to get enough fluid... Perhaps?... Maybe?... Yes?....
